Unfortunately, we haven't been able to fix the problem yet.
The V_dc supply voltage is approximately DC 43V. Since it is supplied through a transformer, what problems can it cause if the power is supplied over 45V?
I purchase new parts and produce…
Part Number: DRV8870 Hi team,
Issue: the VM pins are burned out at use.
On the script, VREF is 5V, current limiting resistor is 0.2ohm, VM voltage is 24V. The output PWM signal is transmitted as a signal and is not used as a drive motor with a load current…
Part Number: DRV8870 Hi team,
my customer find that the negative voltage ratings will exceed the maximum rating (-0.7V) . The minimum voltage is -0.9V and last for about 100ns.
Will it damage our products and do u have any advice to reduce the minimum…
Part Number: DRV8870 Hello,
My customer is considering using the DRV8870 for DC motor control.
Input power 24V, estimated current consumption is 1A.
They assume that when controlling a DC motor (converting from CW to CCW or Pause), a reverse current will…
Part Number: DRV8850 Other Parts Discussed in Thread: DRV8870 , Hi Ti experts,
Why does DRV8850 have 4x input pin to control H bridge. Correspondingly, the DRV8870 has only 2x input.
What are the application scenarios of the four inputs.
In DRV8850 datasheet…
Part Number: DRV8870 Other Parts Discussed in Thread: DRV8770 DR8870 does not have an emergency stop function, the impact force is too large when the motor is stopped in an emergency, the full-bridge circuit used in the past, controlled by the SD foot…
Hi Pablo,
Pablo Armet said: I will close this ticket since it seems the issues was probably caused by overheating on the IC pins. If you observe the same issue on another IC, you can submit a new question. chenzhuang said: If there is a specific soldering…
Hi Cherry,
Can you provide more information if possible?
Based on the attached waveforms, there are quite a lot of issues that I can see.
Startup waveform is quite unstable. The current dips down to -2A for a short amount of time and then oscillates…
